Abstract

A system (100) for repairing a damaged blade (102) of a gas turbine engine (10) includes a sacrificial build platform (106, 106-1, 106-2) configured to be positioned and fused with the damaged blade (102) proximal to at least one stub portion (108, 108-1, 108-2) of the damaged blade (102). The at least one stub portion (108, 108-1, 108-2) protrudes from a root (110) of the damaged blade (102) and defines a deposition surface (112). The sacrificial build platform (106, 106-1, 106-2) includes a base (114) defining a pair of cavities (116a, 116b). The at least one stub portion (108-2) includes a pair of projections (108a, 108b), each cavity (116a, 116b) is configured to receive a corresponding projection (108a, 108b) from the pair of projections (108a, 108b). The system (100) further includes an additive manufacturing system (150) that is configured to deposit material on the base (114) of the sacrificial build platform (106, 106-1, 106-2) and the deposition surface (112) of the at least one stub portion (108, 108-1, 108-2) to form a base structure (118) of a repaired blade (122).
